I also have the Rivershed boots. They perform very well on all types of surfaces in the water. However, I think they outperform felt by a long shot on the bank and on the trail to the river. They do not freeze up in the winter once they get wet, and they do not wear out as fast if you fish in spots which might require a short walk to the river or lake. As for states that currently ban them or might ban them in the future, I think this is a mute point. The industry is headed toward rubber soles whether anyone likes it or not. Every major manufacturer now sells rubber soles as on their top of the line boots.
